A waveform is a graphical representation of the variation of a signal over time, typically illustrating how the amplitude, frequency, and phase of the signal change. It is fundamental in fields like acoustics, electronics, and physics, where understanding waveforms is crucial for analyzing and manipulating signals.

Telecommunications is the transmission of information over significant distances by electronic means, enabling communication between individuals, businesses, and governments across the globe. It encompasses a wide range of technologies, including telephones, radio, television, and the internet, playing a crucial role in modern society by facilitating instant communication and data exchange.

Broadcasting in programming, particularly in languages like Python, allows operations to be performed on arrays of different shapes by automatically expanding the smaller array to match the shape of the larger one. This feature optimizes computational efficiency and simplifies code by eliminating the need for explicit loops or reshaping of data arrays.

medium for transmitting data

Communication channels are the mediums through which information is transmitted from a sender to a receiver, influencing the effectiveness and clarity of the message. They can be formal or informal, verbal or non-verbal, and are chosen based on factors such as audience, context, and the nature of the message.
